I can't say I have enjoyed reading "A Line Made by Walking" by Sara Baume at all.
This book is a victim of bad marketing, as far as I'm concerned: I love animals in general, and foxes in particular, so of course I'll pick up every book that has a fox on its cover.
I could never have imagined that what I would find inside was just a collection of

photos of dead animals (including the fox). Who in their right mind thought it was a good idea to design a cover and write a blurb that appeals to nature lovers, when the actual book is an endless collage of slaughtered animals?
Also, I've read other novels that deal with animal deaths, and those other novels haven't disturbed me half as much as this one did. I think it was the heartless, uncaring way those deaths were handled here that really upset me.

Overall, I think the publisher did the book a disservice by advertising it as something that it's not, because the wrong kind of reader is going to buy it and not enjoy it, whereas the readers who might actually enjoy this kind of work won't be buying it, due to the cover art making it look like something else.
